OVEN-DOOR FOR COOKING STOVES OR RANGES.

SPECIFICATION forming part of Letters Patent No. 526,974, dated October2, 1894.

Application filed February 17, 1894. Serial No. 500,567. (No model.)

v citizen of the United States, residing at Portsmouth, in the county ofScioto and State of Ohio, have invented a new and useful Improvement inOven-Doors for Cooking Stoves or Ranges, which improvement is fully setforth in the following specification and ac companying drawings, inwhich Figure I is an elevation of the inner sid of the skeleton frame ofmy improved oven door for cooking stoves, ranges, &c.; Fig. II, asection on line a: a: of Fig. I; Fig. III,'a modified form of attachingthe stay plate to the frame, and Fig. IV an elevation of the.

door in complete form.

My invention relates to improvements in the construction of oven doorsfor cooking stoves and ranges, and its purpose is to provide a simpleand practical remedy for a defeet which has interfered With the generaladoption of the doors adapted to swing vertically on trunnions or hingesattached to their lower edges, and which may be opened or closedbyalever operated by the foot. When thrown open in -thatmanner, theirentire weight falls upon brackets which stop them at a horizontalposition and they frequently give way and break at or near thetrunnions. Attempts have been made to correct the evil by the use ofmalleable iron for the doors, but it has been discovered that while theyresist fracture, they will bend and be thus unfitted to close the oven.

My invention consists in constructing the doors in such a manner thattheir strength will be greatly increased and their weight materiallydiminished.

The peculiar advantages of the device will be readily understood byreferring to the accompanying drawings in which A designates the frameor skeleton of the door, which may be made of cast metal having flangededges united at intervals by integral ribs 2 which face of the framewhich is highly polished Y and nickel plated. In order to resist thestrain which is generally confined to the lower corners of the ,door, orthe adjoining parts, the metal is reinforced. as at. The

side and lower rails of the frame are rabbeted as at 5 to receive asteel'plate 6 which is perforated for the rivets 3 by which it issecurely clamped upon the frame. If preferred, the lower edge of theplate may be flanged and adapted to engage the lower rail of the frameas shown in Fig. 3.

It is obvious that the steel plate may be readily cut by a suitable dieand accurately fitted in the frame and that it operates as a stay or tiewhich will successfully resist any force that may be brought to bearupon the door.

It is also evident that while this'invention is applicable to all ovendoors of the class referred to, it will prove a convenient ad junct tothe device described in my Patent No. 483,117, issued September 20,1892.

What I claim as new is- In an oven door for cooking stoves, ranges,

and other similar objects, the combination FRANK V. KNAUSS.
